The AZ496MTR-G1 is a high-voltage AC-DC controller manufactured by Diodes Incorporated, designed for offline power supply applications. It integrates a high-voltage current source to eliminate the need for external startup resistors, thereby reducing standby power consumption. The device features an internal oscillator with frequency jittering to minimize electromagnetic interference (EMI). It supports both primary-side regulation and secondary-side sensing for improved load regulation. Key protection mechanisms include overvoltage protection, cycle-by-cycle current limiting, and thermal shutdown. The component is available in a surface-mount package suitable for compact designs.
